Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...

background: hemoptysis occurs due to either pulmonary diseases or bronchoscopy interventions. the aim of the present study was to compare the efficacy of the endobronchial instillation of adrenaline with that of tranexamic acid. methods: fifty patients were randomly selected as 2 double-blinded sample groups (n=25). in these patients, bleeding could not be controlled with cold saline lavage dur...

introdution: tuberculosis (tb), with different types of respiratory tract involvements, has a high rate of mortality all around the world. endobronchial involvement, which is a slightly common tuberculous infection, requires special attention due to its severe complications such as bronchostenosis. aim of study of this study was describes, one type of pulmonary tuberculosis with less diagnosed ...

I tracheobronchial injuries are fatal complications requiring immediate diagnosis and treatment. Unintentional one sided intubation, endotracheal tube cuff over-inflation, direct trauma with guides or boogie’s, double-lumen tube employment, tube replacement without cuff deflation and coughing against closed or blocked ventilation circuits are the possible causes.1, 2 Emergency or difficult intu...

OBJECTIVES Ever since the discovery of Mycobacterium tuberculosis in 1882, many diagnostic methods have been developed. However "The gold standard" for the diagnosis of tuberculosis (TB) is still the demonstration of acid fast Bacilli (AFB) by microscopic examination of smear or bacteriological confirmation by culture method. MATERIALS AND METHODS In suspected 75 patients with active pulmonar...

BACKGROUND Sampling of peripheral pulmonary nodules with radial endobronchial ultrasound (p-EBUS) increases diagnostic yield of bronchoscopy. However, diagnostic yield is influenced by numerous factors. OBJECTIVE We evaluated the use of SpyGlass, a one millimeter diameter optic fiber, to obtain images of the distal mucosa and of pulmonary lesions detected with p-EBUS to determine if visual as...

Fiber-optic bronchoscopy is a safe and useful diagnostic and therapeutic tool for the management of the pulmonary diseases. The purpose of this study was to find out the demographic profiles, indications, bronchoscopic findings, and diagnoses of the patients who underwent bronchoscopic examination. Retrospective analysis of 231 consecutive bronchoscopies done in Nepal Medical College Teaching H...
